LoRaWAN Health V2
The overall goal being to monitor the health status of hundreds of persons at a time within a perimeter of few hundred meters. The typical scenario is for outdoor groups , possibly elderly persons in retirement houses, outdoor workers under a tough weather, health-fragile children in schools, etc...
It is a Fullstack IoT system to gather data from the wearer of our LoRaWAN enabled custom wristwatches.
This is the next version of the LoRaWAN Health V1 with a new backend, new device, and adapted mobile app. It uses AWS services with AWS CDK for a simple and faster deployment to production compared to the containerized version. Services such as AWS wireless (LoRaWAN), cognito, dynamodb and timestream increased the development speed as well as reducing its cost.
The device consist of two Rigid/Flex PCBs with a sandwiched round battery, placed inside a wrist worn garment. It measures the wearer heart-rate, temperature and movement to gather data in order to detect abnormal vital signs.
Key Points:
- Serverless with AWS-CDK
- AWS LoRaWAN Broker
- Fast to enter in production
- Rigid/Flex PCB assembly

This project page has been separated into to project pages 'LoRaWAN Health V1' and 'LoRaWAN Health V2' as they represents two distinct approach to its backend development.
The previous version used docker with self-managed services with quite a few moving parts and hence higher development complexity (for a team of 1 person).
In this version I moved to a totally different architecture with AWS services which enabled for a much quicker development and much lower operation complexity, at the price of vendor lock-in.
